Age ain’t nothing but a number. If you think it’s too late to get a college degree, be inspired by 99-year-old Doreetha Daniels, who became the oldest graduate at the College of the Canyons last week. And if you want to adopt a 76-year-old daughter, meet the remarkable 92-year-old Muriel Clayton of Dallas, Texas. Clayton has acted as a mother to Mary Smith for more than 60 years. When Smith was 11 years old, her father passed away and her mother was ill, so Clayton took her under her wing. Clayton has wanted to adopt Smith for six decades, but she thought it would be respectful to wait until Smith’s biological mother, who was ill, passed away. On the day before this past Mother’s Day, Clayton and Smith discussed the adoption, which became formal on Tuesday, June 9, at the Dallas County Court. “I have worked jigsaw puzzles, and my life had been a beautiful picture,” Clayton said. “But one piece was missing, and that was Mary. And now I’ve got that piece in place.”
